9 Claims.

This invention relates to the manufacture of pile carpets and rugs andis more particularly directed to a setting frame or machine for windinga series of yarns side by side on a receiver or spool.

In accordance with the present practice in winding a series of yarns ona receiver or spool by a setting machine or frame, a presser roll isordinarily employed to act upon the receiver or spool and the yarn as itis wound thereon, and the pressure of the roll upon the yarn isregulated by weights and levers, or by springs connected to a slidingmember which supports the presser roll. The compactness of the yarn uponthe receiver or spool depends, of course, on the pressure exerted by thepresser roll. The pressure on the presser roll is required to beregulated and changed from time to time to suit thevarying conditionsthat arise in use, and when the required amount of yarn has been woundon the receiver or spool it is necessary to disengage the presser rollfrom the yarn on the receiver or spool and the operator has beenrequired to lift the presser roll by hand the required distance toremove the presser roll from the yarn on the receiver or spool, and tofurther provide a clearance over the yarn in order to swing the presserroll forwardly to permit removal of the wound receiver or spool. Also,when it is required to insert or engage an empty spool with itsoperating means, when the presserr roll is down in working position, theoperator must again lift the presser roll by hand the full distance ofthe vertical lift.

One of the objects of the present invention is to provide means for theelimination of the labor fatigue of the operator in lifting the toproll, as

- described, and further to provide means for eX- erting amore uniformand consistent pressure of the presser roll on the winding yarn thanheretofore, which uniform pressure insures a more evenly wound receiverAor spool of uniform compactness or density. A further object of the in-4vention is to provide means for perfecting the best be made clear fromthe following description and accompanying drawing of one good formthereof.

The drawing presents a side elevation of a setting machine or frameembodying the present invention.

The frame I of the machine may be of any usual type for the support ofthe operating parts, and mounted for rotative movement on the machineframe are the operating rollers 2 and 3 for rotating the yarn receiveror spool. The operating rollers 2 and 3 may be conveniently driven fromthe main driving shaft 4 but the driving connection between the drivingshaft and operating rollers is not herein shown because it forms noessential part of the present invention.

Mounted in suitable guides 5 is a presser roll supporting memberconstituted in the present instance as a slide 6 which at its upper endat 'i supports the presser roll 8 and in order that the presser roll maybe swung to one side to permit the wound receiver or spool to be removedfrom the machine the upper portion 1 of the presser roll supportingmeans is pivoted at 9 to the slide B.

When the parts thus far described are in their 'operative relation thereceiver or spool I!) rests upon the operating rolls 2 and 3 while thepresser roll 8, as will more fully appear, presses upon the yarnreceiver or spool and the yarn load as it gradually increases in amount.

Associated with the parts thus far described is a cylinder I I, shown inthe present instance as located at the lower part of the machine frame,and operating in the cylinder II is a piston i2. and extendingtransversely of the machine or setting frame is a shaft I3 having an armI4 affixed thereto at each side of the machine.

Connected to each of the arms I4, one at each side of the machine, is aconnecting rod I 5 which at its upper end is joined at I6 to anadjustable member I1 supported by a stud I8 secured to the presser rollsupporting means, the construction being such that upon movement of thearms clockwise or contra-clockwise, the presser roll supporting meanswill have movements imparted thereto either in a downward or an upwarddirection.

Secured to the transverse shaft I3 is an arm I9 having a slotted endportion 20 which is engaged at 2| with the piston rod 22, wherebymovement of the piston and piston rod will be imparted to the transverseshaft I3 and through the arms I4, hereinbefore described, such movementswill be imparted to the presser roll 8.

In accordance with the present invention the presser roll is to be givenits desired movements through fliud pressure in the cylinder I I.

Mounted at a convenient position on the machine frame is a controllingvalve 23 for controlling the fluid pressure as it comes from the sourceof supply through the pipe 24, and connected with the valve is theconduit or pipe 25 which communicates at 26 with the fluid pressurereduction valve 21 which may be of any of the usual forms of suchvalves.

Connected to the lower portion of the fluid pressure reduction valve isa pipe or conduit 28 which has the downwardly extending portion 29connected to the cylinder II above the piston I2, the construction beingsuch that when the control valve 23 is set for the ingress of uidpressure to and through the reduction valve 21, such pressure will beexerted above the piston I2 and perforce exert a downward pressure ofthe presser roll 8 upon the yarn on the receiver being wound.

Communicating with the controlling valve 23 is a conduit or pipe 30which extends downwardly and communicates at 3I with the lower portionof the cylinder II below the piston I2, and in order that the flow offluid pressure to and through the reduction valve 21 or to and throughthe pipe or conduit 30 may be controlled, the controlling valve 23 isprovided with a manually operated handle or means 32.

Associated with the controlling valve 23 is an exhaust port 33 which,when the handle 32 of the controlling valve is in the full lineposition, as shown, will communicate with the outside atmosphere andpermit pressure in the pipe or conduit 30 to exhaust. When, however, thehandle 32 is moved to the dotted line position, as indicated, theexhaust port is closed and fluid pressure from the source of supply willpass through the pipe 30 to the lower part of the cylinder below thepiston I2.

Connected to the upper portion of the cylinder II is a relief valve 34of usual construction, and connected to the lower portion of thecylinder below the piston is another relief valve 35.

Assume that the yarn receiver or spool I is in position for winding, asshown, and in contact with the operating rollers 2 and 3 and the presserroll 8, and that the series of yarns a to be wound upon the receiver orspool are presented, as

usual, the piston I2 in the cylinder II will be at its lowest position,as shown, and the operating lever or handle 32 will be in the positionshown by full lines in the drawing, with the result that fluid pressurewill pass through the controlling valve 23 to the pressure reductionvalve 21 and be admitted to the top portion of the cylinder I I abovethe piston, so that as the load of yarn upon the receiver or spoolprogresses and the yarn load increases in size the piston will be drawnupwardly by the presser roll against the fluid pressure admitted to thetop of the cylinder. At this time the exhaust port 33 will be open tothe atmosphere to permit the piston to rise under the dictates of thepresser roll against the uid pressure.

When the required amount of yarn or yardage has been wound on thereceiver or spool 4, the sett-ing frame automatically stops under theaction of any of the usual automatically acting stop devices. Theoperator then moves the lever 32 from its full to its dotted lineposition, as shown. This change in the controlling valve changes anddiverts the direction of fluid pressure from the source of supplythrough the operating valve into and through the pipe 36 to the bottomof the cylinder below the piston. This pressure, not being reduced, aswas the pressure on top of the piston, forces the piston upwardlyagainst the compression of a valve 34. As the piston continues to rise,the roller 8 also rises and when the presser roll 8 is raised away fromthe yarn on the receiver or spool to its highest position, as shown atthe operator swings the presser roll to a position shown at y at whichtime the full receiver or spool may be disengaged and the next receiveror spool to be wound may be placed in contact with the operating rolls 2and 3, whereupon the presser roll is swung back into its initialposition zr.

With the empty spool in Contact with the operating rollers 2 and 3 andpresser roll 8 in position at :c the operator swings the handle 32operating the valve 23 from the dotted to the full line position whichreverses the air pressure to the top of the piston and the presser rollis thereupon forced to its initial starting position, as indicated byfull lines in the drawing.

As the piston is forced downwardly the action is against the compressionset up by predetermined pressure in the relief valve 35, but at thispoint it is to be noted that the operating valve 23 connects the exhaustport 33 with the pipe 39. When the handle 32 of the controlling valve 23is in position shown by full lines, the exhaust port 33 is open therebypreventing a vacuum under the piston when the piston is rising in thecylinder II, and also when the piston is in its up position and thehandle of the controlling valve is put in its full line position and theair pressure is directed upon the top of the piston, the exhaust portbeing open forms an escape for the compression in the bottom of thecylinder. This is necessary because the relief valve 35 wouldnecessarily be set to a higher pressure than enters on top of the pistonthrough the fluid pressure reduction valve 21. When the handle 32 of thecontrolling valve is in dotted line position the exhaust port 33 isclosed thereby allowing an initial pressure from the source of supply topass into the pipe 3D for raising the presser roll, as previously noted.

The compression at the end of the piston stroke forms a cushion or shockabsorber. Concisely stated, the pressure of the presser roll 8 on theyarn load is produced by air pressure instead of by springs or Weights,as now used, and the control of raising or lowering the presser roll 8is at the disposition of the operator by the manipulation of the valvehandle 32, so that all manual fatigue in manipulating the presser rollsis eliminated.
